Soldier row on top of floor??

I'm really not worried about cutting, I just know that if I start being exact I will get too anal and I want to have fun.

I want to have fun.

I think you'll find that a certain amount of trimming of the inside face of the brick is fun in a puzzle kind of way. Up after the third or forth chain you'll see what you need to do a decent (not perfect) cosmetic fit.

I built mine without beveling- just half bricks until I got towards the top. Then I changed to 1/3 bricks (halves were just too big at that point).

You don't have to do all the beveling and cutting if you don't want to. I had great fun building mine, and it works just fine.

The place you need to worry about is in the waterproofing later- I've had trouble with my igloo enclosure because of waterlogging and then extreme (for here, anyway!) cold. However you choose to enclose the oven, insulate well with good materials and then get it watertight!!!!
